Abstract
The process concerns the cleaning of workpieces exhibiting organic residues, with the use of a fluid introduced under pressure into a pressure tank loaded with the workpieces. According to the invention, the fluid is circulated during the cleaning step, using preferably liquefied gases, e.g. carbon dioxde, as the fluid. By the use of a heat exchanger, the temperature of the fluid can be regulated during the process.
